The OpenFunction function framework is designed to provide users with the ability to convert function code into application that support multiple runtimes.
You can learn more about the design of the OpenFunction Context by visiting function-context.
You can learn more about the different versions of the OpenFunction Context specification by visiting the links below:
The direct user of Context is the OpenFunction Builder (Go) and the following is a compatible relationship between Context, Builder and OpenFunction.
You can get the corresponding version compatibility information in the specific builder repository. Here we use the OpenFunction Go (v1.15) builder as an example.
| OpenFunction | Context | Builder (Go) |
|---|---|---|
| v0.3.* | v0.1.0 | v0.2.2 (openfunction/builder-go:v0.2.2-1.15) |
| v0.4.* | v0.2.0 | v0.3.0 (openfunction/builder-go:v0.3.0-1.15) |
| v0.5.* | v0.2.0 | v0.4.0 (openfunction/builder-go:v0.4.0-1.15) |

HTTP
The framework creates a route that associates the "/" url path and the user function. After that, it starts the HTTP service according to the PORT parameter.
-
CloudEvent
The CloudEvent provides a handler for handling HTTP requests while binding user function. The framework creates a route that associates the "/" url path and the CloudEvent HTTP handler. After that, it starts the HTTP service according to the PORT parameter.

OpenFunction
This function type is an implementation of Data Bindings
The framework creates a route that associates the specified HTTP url path with the user function.
The framework also provides the SDK for getting data and sending data. Users can use OpenFunction Context to handle function resource contexts, including performing "get data" and "send data".
